java中类序列化与反序列化的实现

private static java.lang.Object ByteToObject(byte[] bytes)...{
java.lang.Object obj;
try {
//bytearray to object
ByteArrayInputStream bi = new ByteArrayInputStream(bytes);
ObjectInputStream oi = new ObjectInputStream(bi);

obj = oi.readObject();

bi.close();
oi.close();
}
catch(Exception e) ...{
System.out.println("translation"+e.getMessage());
e.printStackTrace();
}
return obj;
}

public byte[] ObjectToByte(java.lang.Object obj)
...{
byte[] bytes;
try {
//object to bytearray
ByteArrayOutputStream bo = new ByteArrayOutputStream();
ObjectOutputStream oo = new ObjectOutputStream(bo);
oo.writeObject(obj);

bytes = bo.toByteArray();

bo.close();
oo.close();
}
catch(Exception e) ...{}
